Abstract

An application element (16) has a wetting body (18) partially received in an inner tube (14) received in an outer tube. Application of pressure on the applicator produces fluid communication between the inner space of the inner and outer tubes. The inner tube is softer than the outer tube such that the bottom of the inner tube deforms upon application of pressure.

Description

Die Erfindung betrifft eine Applikationsvorrichtung, gemäß dem Oberbegriff von Anspruch 1.The invention relates to an application device, according to the preamble of claim 1.

Aus der US-PS 5,573,340 ist ein Container für die Verteilung eines flüssigen oder pulverförmigen Produktes bekannt, bei dem ein Schwamm mit einer Flüssigkeit benetzbar ist.From US-PS 5,573,340 a container for the distribution of a liquid or powdery product is known in which a sponge is wetted with a liquid.

Für das Aufbringen von Substanzen ist es seit langem bekannt, einen ersten Bestandteil in einer ersten Kammer und einen weiteren Bestandteil in einer zweiten Kammer aufzubewahren und durch Druck von außen eine Sollbruchstelle, die die beiden Bestandteile trennt, zu brechen und hierdurch die Bestandteile zu der Substanz zu vermischen. Hierzu sei beispielsweise auf die DE-AS 2 024 402 verwiesen.For the application of substances, it has long been known to store a first component in a first chamber and a further component in a second chamber and to break by pressure from outside a predetermined breaking point which separates the two components, and thereby the components to the substance to mix. Reference is made, for example, to DE-AS 2 024 402.

Applikationsvorrichtungen mit Applikationselementen sind ebenfalls seit langem bekannt, wozu beispielhaft auf die DE-GM 92 189 49 verwiesen wird. Über seitliche Löcher in einer Innenhülse kann eine Fluidverbindung zwischen dem Innenraum der Innenhülse und dem Innenraum der Außenhülse erzeugt werden. Diese Lösung ist für den Kosmetikbereich geeignet. Wenn es darum geht, dass die Bestandteile im Innenraum der Innenhülse und im Innenraum der Außenhülse erzeugt werden. Diese Lösung ist für den Kosmetikbereich geeignet. Wenn es darum geht, dass die Bestandteile im Innenraum der Innenhülse und im Innenraum der Außenhülse voneinander getrennt gelagert werden müssen, ist dies Lösung jedoch weniger geeignet.Application devices with application elements have also long been known, for which reference is made, for example, to DE-GM 92 189 49. Via lateral holes in an inner sleeve, a fluid connection between the interior of the inner sleeve and the interior of the outer sleeve can be generated. This solution is suitable for the cosmetics sector. When it comes to the fact that the components are generated in the interior of the inner sleeve and in the interior of the outer sleeve. This solution is suitable for the cosmetics sector. When it comes to the fact that the components in the interior of the inner sleeve and in the interior of the outer sleeve must be stored separately, this solution is less suitable.

Ferner ist aus der DE-OS 44 158 54 eine Misch- und Applikationskapsel für Dentalzwecke bekannt. Bei dieser Lösung werden die Bestandteile dadurch vereinigt, dass über ein spitzes Element eine Folie zwischen den Bestandteilen durchstochen wird.Furthermore, from DE-OS 44 158 54 a mixing and application capsule for dental purposes known. In this solution, the components are combined by puncturing a film between the components via a pointed element.

Zahlreiche weitere Applikationsvorrichtungen sind bekannt geworden. So ist es beispielsweise vorgeschlagen worden, ein Applikationselement in einer Flüssigkeit eingetaucht zu halten und durch Niederdrücken des Behälters für diese Flüssigkeit nach der Art eines Überlaufs eine weitere Flüssigkeit einströmen zu lassen, um die aufzubringende Substanz bereitzustellen. Diese Lösung bedarf allerdings zweier getrennter Abdichtsysteme, so dass ein nicht unbeachtlicher Aufwand erforderlich ist. Eine Vielzahl von Dichtlinien bedingt allerdings auch eine entsprechend große Anfälligkeit und Lagerinstabilität.Numerous other application devices have become known. For example, it has been proposed To keep application element immersed in a liquid and to flow by depressing the container for this liquid in the manner of an overflow another liquid to provide the substance to be applied. However, this solution requires two separate sealing systems, so that a not inconsiderable expense is required. However, a large number of sealing lines also requires a correspondingly high susceptibility and bearing instability.

Ferner ist es in der deutschen Patentanmeldung 199 56 705.0 vorgeschlagen worden, ein Applikationselement mit einem Benetzungskörper in einer Innenhülse teilweise aufzunehmen und die Innenhülse in einer Außenhülse aufzunehmen. Durch Druck auf das Applikationselement soll eine Flüssigkeitsverbindung zwischen dem Innenraum und der Innenhülse und dem Innenraum der Außenhülse erzeugt werden. Diese Lösung bietet im Grunde eine gute und einfache Abdichtung der beiden Bestandteile zur Bereitstellung der Substanz. Allerdings muß die Außenhülse zur Bereitstellung der Dichtlippen aus einem etwas elastischem Material hergestellt werden, damit ein flüssigkeitsdichtes Anliegen der Dichtlippe zwischen Innenhülse und Außenhülse gewährleistet ist. Andererseits ist es wichtig, dass die in den Innenraum der Außenhülse aufgenommene Substanz auch über eine längere Zeit sicher gelagert werden kann. Um dies zu erzielen, ist eine recht große Wandstärke vorgesehen.Furthermore, it has been proposed in German Patent Application 199 56 705.0 to partially receive an application element with a wetting body in an inner sleeve and to receive the inner sleeve in an outer sleeve. By pressure on the application element a fluid connection between the interior and the inner sleeve and the interior of the outer sleeve is to be generated. This solution basically provides a good and easy seal of the two ingredients to provide the substance. However, the outer sleeve to provide the sealing lips must be made of a slightly elastic material, so that a liquid-tight concern of the sealing lip between the inner sleeve and outer sleeve is ensured. On the other hand, it is important that the substance absorbed in the interior of the outer sleeve can be safely stored for a long time. To achieve this, a fairly large wall thickness is provided.

Teilweise werden aber auch Lösungsmittel wie Aceton, Äthylalkohol, usw. für die Bestandteile der Substanz eingesetzt. Derartige Lösungsmittel weisen einen ausgesprochen hohen Dampfdruck auf und diffundieren auch dann durch die Außenhülse, wenn sie eine recht große Wandstärke aufweist.In some cases, however, solvents such as acetone, ethyl alcohol, etc. are used for the constituents of the substance. Such solvents have a very high vapor pressure and also diffuse through the outer sleeve, if it has a fairly large wall thickness.

Zwar ist es an sich bekannt geworden, einem hohem Dampfdruck durch das Aufbringen zusätzlicher Schichten, wie beispielsweise einer metallischen Beschichtung, zu begegnen. Problem hierbei ist, dass zweischichtige Materialien bei deren Verarbeitung und der Entsorgung problematischer sind und auch keine vollständige Dampfsperre möglich ist. Zwar könnte die metallische Beschichtung auch innen aufgebracht werden. Dann erstreckt sie sich aber über die dortigen Dichtlippen hinweg, so dass die Dichtwirkung vermindert ist. Zudem verteuert die Bereitstellung einer metallischen Beschichtung die Herstellung der Applikationsvorrichtung, wobei die Herstellungskosten gerade bei Realisierung einer Single-Dose-Einheit wichtig sind.Although it has become known per se to counteract a high vapor pressure by the application of additional layers, such as a metallic coating. Problem here is that two-layer materials in their Processing and disposal are more problematic and no complete vapor barrier is possible. Although the metallic coating could also be applied internally. But then it extends beyond the local sealing lips, so that the sealing effect is reduced. In addition, the provision of a metallic coating makes the production of the application device more expensive, whereby the production costs are particularly important when implementing a single-can unit.

Daher liegt der Erfindung die Aufgabe zugrunde, eine preisgünstig herzustellende Applikationsvorrichtung für das Auftragen einer Substanz gemäß dem Oberbegriff von Anspruch 1 zu schaffen, die auch für Lagerzeiten von mehr als einem Jahr und auch für Substanzen mit hohem Dampfdruck geeignet ist.Therefore, the invention has for its object to provide an inexpensive to produce application device for applying a substance according to the preamble of claim 1, which is also suitable for storage periods of more than a year and also for substances with high vapor pressure.

Diese Aufgabe wird erfindungsgemäß durch Anspruch 1 gelöst. Vorteilhafte Weiterbildungern ergeben sich aus den Unteransprüchen.This object is achieved by claim 1. Advantageous developments emerge from the subclaims.

Erfindungsgemäß besonders günstig ist es, dass die Realisierung der Innenhülse aus einem weicheren Material es erlaubt, die Dichtfunktion durch die Innenhülse selbst sicherzustellen und die Außenhülse aus einem spröden und hochdichten Material zu realisieren. Diese Lösung ist preisgünstig, denn die Wandstärke der Außenhülse kann so reduziert werden und dennoch die Lagerstabilität aufgrund der verbesserten Dampfdruckdichtheit bereitgestellt werden.According to the invention, it is particularly favorable that the realization of the inner sleeve made of a softer material makes it possible to ensure the sealing function by the inner sleeve itself and to realize the outer sleeve of a brittle and high-density material. This solution is inexpensive, because the wall thickness of the outer sleeve can be reduced and still the storage stability can be provided due to the improved vapor pressure tightness.

Die erfindungsgemäß erwünschte Weichheit und Verformbarkeit der Innenhülse läßt sich sowohl materialspezifisch als auch durch die Gestaltung der Innenhülse bereitstellen. Wenn ein Verformungselement eine einseitig wirkende radiale Kraft auf den Boden der Innenhülse oder einen bodennahen Bereich der Innenhülse ausübt, kollabiert die Innenhülse dort mindestens teilweise, so dass die Abdichtung zwischen Innenhülse und Außenhülse in der erwünschten Weise verloren geht.The inventively desired softness and deformability of the inner sleeve can be provided both material-specific and by the design of the inner sleeve. If a deformation element exerts a unilaterally acting radial force on the bottom of the inner sleeve or a region near the bottom of the inner sleeve, the inner sleeve collapses there at least partially, so that the seal between the inner sleeve and Outer sleeve is lost in the desired manner.

Erfindungsgemäß ist es bevorzugt, wenn die Dichtlippe sich ringförmig im bodennahen Bereich an der Innenhülse nach außen erstreckt. Die Wand der Außenhülse kann damit innen bis zum Verformungselement hin völlig glatt ausgebildet sein.According to the invention it is preferred if the sealing lip extends annularly in the ground-level region on the inner sleeve to the outside. The wall of the outer sleeve can thus be made completely smooth inside up to the deformation element.

Erindungsgemäß besonders günstig ist es, wenn der Boden der Innenhülse recht dünn ausgebildet ist. Durch den einseitigen und massiven Keil, der das Verformungselement bilden kann, wird bei einem entsprechend dünnen Boden die Innenhülse verformt, auch wenn die Materialeigenschaften von Innenhülse und Außenhülse sich nur um Weniges unterscheiden. Insofern ist die Formunlierung weicher auch in dem Sinne "nachgiebiger" zu verstehen, und bei Bedarf kann auch die Innenhülse aus einem recht harten Material bestehen, vorausgesetzt, die erwünschte Dichtfunktion ist sichergestellt.According to the invention, it is particularly favorable if the bottom of the inner sleeve is made quite thin. Due to the one-sided and massive wedge, which can form the deformation element, the inner sleeve is deformed in a correspondingly thin bottom, even if the material properties of inner sleeve and outer sleeve differ only slightly. In this respect, the Formunlierung softer also in the sense of "compliant" to understand, and if necessary, the inner sleeve of a fairly hard material, provided that the desired sealing function is ensured.

Gemäß einer besonders günstigen Ausgestaltung der erfindungsgemäßen Applikationsvorrichtung ist das Verformungselement oder der Verformungskörper seitlich an der Innenwand der Außenhülse angebracht und erstreckt sich mit zum Boden der Innenhülse hin zunehmender Tiefe in radialer Richtung spitz zulaufend. Die radiale Tiefe des Verformungselements nimmt zum Boden der Außenhülse hin kontinuierlich zu und beträgt der Innenhülse benachbart zunächst nahezu Null. Hierdurch ist der Einschubwiderstand der Innenhülse recht gering, und die Verformung erfolgt allmählich, während die Innenhülse eingeschoben wird.According to a particularly advantageous embodiment of the application device according to the invention, the deformation element or the deformation body is mounted laterally on the inner wall of the outer sleeve and extends to the bottom of the inner sleeve towards increasing depth in the radial direction tapered. The radial depth of the deformation element increases towards the bottom of the outer sleeve towards continuously and is adjacent to the inner sleeve initially almost zero. As a result, the insertion resistance of the inner sleeve is quite low, and the deformation takes place gradually, while the inner sleeve is inserted.

Das Verformungselement kann entweder an seiner Oberseite ballig ausgebildet sein oder eine Schneide aufweisen. Bei der Ausgestaltung mit der Schneide ist es auch möglich, die harten Materialeigenschaften der Außenhülse so auszunutzen, dass der Boden der Innenhülse oder insbesondere ein oder mehrere Dichtringe regelrecht angeschnitten werden. Bei dieser Lösung sind dann Öffnungen in der Innenhülse im Grunde entbehrlich, wobei es sich versteht, dass beliebige geeignete Verformungselemente eingesetzt werden können, um eine Flüssigkeitsverbindung zwischen dem Innenraum der Innenhülse und dem Innenraum der Außenhülse herzustellen.The deformation element can either be crowned on its upper side or have a cutting edge. In the design with the cutting edge, it is also possible to exploit the hard material properties of the outer sleeve so that the bottom of the inner sleeve or in particular one or more sealing rings are cut to size. At this Solution are then openings in the inner sleeve basically dispensable, it being understood that any suitable deformation elements can be used to establish a fluid connection between the interior of the inner sleeve and the interior of the outer sleeve.

Es ist auch möglich, den Dichtring als einen in einer Nut an der Innenhülse geführten O-Ring auszubilden. Bei dieser Lösung kann dann die Schneide den O-Ring zerschneiden. Er zieht sich zusammen und gibt einen Bereich frei, in dem das Fluid über Öffnungen in den Innenraum der Innehülse strömen kann.It is also possible to form the sealing ring as a guided in a groove on the inner sleeve O-ring. In this solution, then the cutting edge can cut the O-ring. It contracts and releases an area in which the fluid can flow through openings in the interior of the inner sleeve.

Es versteht sich, daß die Nut dann so gestaltet sein sollte, daß sie die Schneidwirkung der Schneide nicht behindert, sondern eher erleichtert.It is understood that the groove should then be designed so that it does not hinder the cutting action of the cutting edge, but rather facilitates.

Auch wenn die Realisierung eines asymmetrischen Verformungselements bevorzugt ist, ist es ohne weiteres auch möglich, zwei einander gegenüberliegende Verformungskörper vorzusehen, die die Innenhülse einquetschen und so den Spalt als Überlaufkanal zwischen dem Innenraum der Innenhülse und dem Innenraum der Außenhülse erzeugen. Es ist ohne weiteres möglich, den Verformungskörper in beliebiger geeigneter Weise auszugestalten, wobei sich bevorzugt unmittelbar neben ihm eine Innenecke erstreckt, die ein Überströmen an dem Boden der Innenhülse entlang erlaubt.Even if the realization of an asymmetric deformation element is preferred, it is also readily possible to provide two mutually opposite deformation bodies, which squeeze the inner sleeve and thus produce the gap as an overflow channel between the interior of the inner sleeve and the interior of the outer sleeve. It is readily possible to design the deformation body in any suitable manner, preferably immediately adjacent to it extends an inner corner, which allows an overflow at the bottom of the inner sleeve along.

Das Applikationselement weist einen Benetzungskörper auf, der bei Bedarf entweder bereits vorab mit einer Reaktionssubstanz versehen ist, oder vor der Applikation mit einer Reaktionssubstanz versehen wird. Der Benetzungskörper kann in beliebiger geeigneter Weise ausgebildet sein, beispielsweise als Pinsel oder als Schaumkörper, der auf einem Stil des Applikationselements aufgebracht ist.The application element has a wetting body which, if necessary, is already provided in advance with a reaction substance, or is provided with a reaction substance before application. The wetting body may be formed in any suitable manner, for example as a brush or as a foam body, which is applied to a style of the application element.

Es ist auch möglich, das Applikationselement selbst separat zu liefern und so eine unterschiedliche Kombination von Bestandteilen für die Bereitstellung der Substanz zu ermöglichen, wobei die Tatsache ausnutzbar ist, dass die Applikationsvorrichtung auch ohne Applikationselement abdichtet.It is also possible to separate the application element itself provide and allow a different combination of ingredients for the provision of the substance, the fact is exploitable that the application device seals even without application element.

Weitere Vorteile, Einzelheiten und Merkmale ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der Zeichnung.Further advantages, details and features will become apparent from the following description of an embodiment with reference to the drawing.

Die in Fig. 1 dargestellte Applikationsvorrichtung 10 weist eine Außenhülse 12 auf, die ein Gehäuse bildet. In der im wesentlichen becherförmigen Außenhülse ist eine Innenhülse 14 geführt, die erfindungsgemäß in besonderer Weise ausgestattet ist. Die Innenhülse 14 ist dafür bestimmt, ein Applikationselement 16 aufzunehmen, das aus Fig. 2 ersichtlich ist und einen Benetzungskörper 18 aufweist.The application device 10 shown in FIG. 1 has an outer sleeve 12 which forms a housing. In the substantially cup-shaped outer sleeve, an inner sleeve 14 is guided, which is equipped according to the invention in a special way. The inner sleeve 14 is intended to receive an application element 16, which can be seen in FIG. 2 and has a wetting body 18.

Die Außenhülse 12 ist länger als die Innenhülse 14 und ist in ihrem unteren Bereich mit einem Fluid 20 versehen, das für die Bereitstellung der Substanz vorgesehen ist.The outer sleeve 12 is longer than the inner sleeve 14 and is provided in its lower portion with a fluid 20 which is provided for the provision of the substance.

Die Innenhülse 14 schließt so einen Bereich der Außenhülse, den Innenraum der Außenhülse 12, ab. Die Innenhülse 14 weist hierzu eine Dichtlippe 24 auf, die sich ringsum erstreckt und dem Boden 26 der Innenhülse 14 benachbart angeordnet ist. Die Innenhülse 14 ist in dem dargestellten Ausführungsbeispiel aus Kunststoff und die Außenhülse 12 ist in dem dargestellten Ausführungsbeispiel aus Glas. Die Dichtlippe 24 kann auf der glatten Innenwand der Außenhülse 12 gut abdichten.The inner sleeve 14 thus closes off a region of the outer sleeve, the interior of the outer sleeve 12. The inner sleeve 14 has for this purpose a sealing lip 24, which extends around and is disposed adjacent to the bottom 26 of the inner sleeve 14. The inner sleeve 14 is in the illustrated embodiment made of plastic and the outer sleeve 12 is in the illustrated embodiment made of glass. The sealing lip 24 can seal well on the smooth inner wall of the outer sleeve 12.

Die Innenhülse 14 weist dem Boden 26 benachbart zwei ziemlich große Öffnungen 28 und 30 auf, die sich seitlich erstrecken. Diese Öffnungen sind von dem Fluid 20 bei eingedrückter Innenhülse 14 leicht und schnell durchströmbar.The inner sleeve 14 has adjacent the bottom 26 two fairly large openings 28 and 30 extending laterally. These openings can be easily and quickly flowed through by the fluid 20 when the inner sleeve 14 is pressed in.

Zur Erzeugung einer Flüssigkeitsverbindung zwischen dem Innenraum der Innenhülse 14 und dem Innenraum der Außenhülse 12 dient erfindungsgemäß ein Verformungselement 34. Das Verformungselement 34 ist in dem dargestellten Ausführungsbeispiel als Keil ausgebildet und weist die aus Fig. 5 ersichtliche Form auf. Der Keil erstreckt sich vom Boden 26 der Innenhülse 14 in dem Zustand gemäß Fig. 1 ausgehend bis zum Boden 36 der Außenhülse 12.To produce a fluid connection between the interior of the inner sleeve 14 and the interior of the outer sleeve 12 is used according to the invention a deformation element 34. The deformation element 34 is formed in the illustrated embodiment as a wedge and has the apparent from Fig. 5 shape. The wedge extends from the bottom 26 of the inner sleeve 14 in the state shown in FIG. 1, starting to the bottom 36 of the outer sleeve 12th

Während aus Fig. 2 ersichtlich ist, in welcher Weise das Applikationselement 16 mit dem Benetzungskörper 18 in die Innenhülse eingesetzt ist, zeigt Fig. 3 das Überströmen des Fluids 20 in die Innenhülse 14 hinein. Durch Druck in Richtung des Keils 36 gemäß Fig. 3 auf das Applikationselement 16 wird zugleich die Innenhülse 14 eingedrückt. Hierzu weist die Innenhülse eine Anschlagschulter 56 auf, die sich mit einem Durchmesser erstreckt, der etwas geringer als der Durchmesser einer Verdickung 58 des Applikationselements 16 ist. Das Ausüben von Druck ist auf diese Weise auf die Innenhülle 14 möglich, ohne dass eine Spitze 54 den Boden 26 berühren muß.While it is apparent from Fig. 2, in which way the application element 16 with the wetting body 18 in the inner sleeve is inserted, Fig. 3 shows the overflow of the fluid 20 in the inner sleeve 14 into it. By pressure in the direction of the wedge 36 according to FIG. 3 on the application element 16, the inner sleeve 14 is at the same time pressed. For this purpose, the inner sleeve has a stop shoulder 56 which extends with a diameter which is slightly smaller than the diameter of a thickening 58 of the application element 16. The application of pressure is possible in this way on the inner shell 14 without a tip 54 must touch the ground 26.

Aus Fig. 4 ist ersichtlich, dass der Benetzungskörper 18 von der Substanz 20 intensiv benetzt ist und die Substanz 20 über das Applikationselement 16 aufgetragen werden kann. In diesem Zustand bildet die Applikationsvorrichtung 10 eine Art Becher für das Auftragen der Substanz, wobei auch ein mehrmaliges Eintauchen des Benetzungskörpers 18 ohne weiteres möglich ist.From FIG. 4 it can be seen that the wetting body 18 is intensively wetted by the substance 20 and the substance 20 can be applied via the application element 16. In this state, the application device 10 forms a kind of cup for the application of the substance, wherein a repeated immersion of the wetting body 18 is readily possible.

Aus Fig. 5 ist ersichtlich, in welcher Weise das Verformungselement 34 ausgebildet sein kann. In dem dargestellten Ausführungsbeispiel ist es im wesentlichen keilförmig mit zwei Spitzen 35 und 37, die einen geringen Gleitwiderstand beim Aufgleiten des Bodens 26 auf das Verformungselement 34 ermöglichen. Es ist ersichtlich, dass seitlich neben dem Verformungselement Innenecken 39 und 41 vorgesehen sind, die ein leichtes Durchströmen der Substanz in den Innenraum der Innenhülse 14 hinein ermöglichen.From Fig. 5 it can be seen in which way the deformation element 34 may be formed. In the illustrated embodiment, it is substantially wedge-shaped with two tips 35 and 37, which allow a low sliding resistance when sliding the bottom 26 on the deformation element 34. It can be seen that inside corners 39 and 41 are provided laterally next to the deformation element, which allow easy passage of the substance into the interior of the inner sleeve 14 inside.

Aus Fig. 6 ist eine weitere Ausführungsform der erfindungsgemäßen Applikationsvorrichtung ersichtlich. In dieser Ausführungsform ist ersichtlich, dass die Innenhülse 14 einen Abschlussring 38 aufweist, an dem sich ein Vorsprung 40 nach außen erstreckt. Dort ist eine Dichtlippe ausgebildet, die bei eingesetztem Applikationselement 16 eine Abdichtung gewährleistet.From Fig. 6, a further embodiment of the application device according to the invention can be seen. In this embodiment, it can be seen that the inner sleeve 14 has a closing ring 38, on which a projection 40 extends to the outside. There, a sealing lip is formed, which ensures a seal when the application element 16 is inserted.

Das Applikationselement 16 weist einen Griff 42 auf. Der Griff schließt sich an eine Verdickung 58 an, an die sich der Schaft 44 anschließt. In diesem Ausführungsbeispiel ist der Benetzungskörper als Mikropinsel 50 ausgebildet. Der Mikropinsel 50 ist in dem dargestellten Ausführungsbeispiel durch eine Beflockung gebildet, so dass sich zahlreiche wirr angeordnete Pinselhaare 52 nach außen erstrecken.The application element 16 has a handle 42. The handle joins a thickening 58, to which the shaft 44 connects. In this embodiment, the wetting body is formed as a micro-brush 50. The micro-brush 50 is formed in the illustrated embodiment by a flock, so that numerous confused brush hairs 52 extend to the outside.

Der Mikropinsel 50 endet in einer eher stumpfen Spitze 54. Diese ermöglicht auch die Kraftübertragung auf den Boden 26 der engen Hülse 14 und damit das Einschieben der Innenhülse 14 zur Aktivierung der Applikationsvorrichtung, wenn die Anlageschulter 56 nicht vorgesehen ist.The micro-brush 50 terminates in a rather blunt point 54. This also allows the power transmission to the bottom 26 of the narrow sleeve 14 and thus the insertion of the inner sleeve 14 for activating the application device when the abutment shoulder 56 is not provided.

Auf dem Mikropinsel 50 kann bei Bedarf eine Reaktionssubstanz bevorzugt als dort abgelagertes Salz aufgebracht sein. Bei dieser Ausführungsform ist unterhalb der Anlageschulter 56 eine Verjüngung 60 oder Kerbe vorgesehen, die die Möglichkeit bietet, den Schaft 44 gegenüber dem Griff 42 abzubiegen. Bei dieser Konfiguration des Applikationselements ist eine plastische Verformung möglich. Auch hier ist es möglich, den Boden 26 über das Verformungselement 34 zu verformen, um ein Benetzen des Mikropinsels 50 mit der Substanz 20 einzuleiten.If necessary, a reaction substance may preferably be applied to the micro-brush 50 as salt deposited there. In this embodiment, a taper 60 or notch is provided below the abutment shoulder 56, which provides the ability to bend the shaft 44 relative to the handle 42. In this configuration of the application element, a plastic deformation is possible. Again, it is possible to deform the bottom 26 via the deformation element 34 to initiate wetting of the micropinsel 50 with the substance 20.
